Summary: This study demonstrates a lignin-first biorefining process for poplar that can produce dissolving cellulose pulp, which can replace cotton production. By expanding poplar plantations, agricultural land previously used for cotton can be reclaimed for food production. Life cycle assessment shows that this approach significantly reduces water consumption compared to cotton production and suggests areas for further improvement.

Summary: Turkey heavily relies on fossil fuels as an energy importing country, leading to environmental issues and energy security concerns. This study in the Marmara Region highlights the potential of using biowastes to meet more than half of the region's electricity demand, providing cost-effective options such as direct combustion of agricultural wastes and conversion of animal wastes to biogas in CHP plants.

Summary: The valorisation of lignin is crucial for the economic viability of the lignocellulosic biorefining industry. The lignin-first biorefining approach, which considers lignin valorisation in the design phase, has been shown to make the fullest use of lignocellulose. Despite the diverse approaches to reporting and analyzing results from lignin-first methods, we propose guidelines for analyzing critical data in order to facilitate direct comparisons between studies.

Summary: The target of achieving carbon neutrality by governments worldwide have given negative emission technologies a crucial role. Algae-based renewable bio-energy is expected to play a larger role in meeting this target. Recent evidence has shown that low doses of toxicants stimulate algae growth, contradicting the belief that toxicants only suppress algae at high doses. Low-dose stress can enhance photosynthesis, growth, biomass, and biochemical quality of algae, suggesting their potential as feedstock for carbon-neutral fuel production. Further scientific developments are needed to improve algae's performance, reduce cultivation costs, and enhance their resilience to toxicant-containing wastewater.

Summary: This study evaluated the bio-recycling of rapeseed straw mixed with chicken manure using black soldier fly larvae for biodiesel and protein production. The results showed that 20% rapeseed straw ratio resulted in high fiber biodegradation, increased larval biomass yield, and lipid accumulation. The addition of 20% rapeseed straw also shortened the larval development time and improved survival rate and conversion efficiency. The produced biodiesel from 20% rapeseed straw had higher saturated fatty acids content and cetane number compared to biodiesel produced from rapeseed oil. Furthermore, the application of black soldier fly larvae technology could reduce CO2 emissions.

Summary: Pakistan has been struggling with electricity shortages since 2005, hindering the country's growth in agriculture, industry, and services sectors. This study used LEAP & REG; software to forecast Pakistan's energy mix from 2022-2050 under baseline and transformation scenarios. The baseline scenario focuses on increasing hydroelectric power, while the transformation scenario emphasizes the use of biomass. The study recommends the transformation scenario due to retiring hydro plants and limited budget for new constructions. By utilizing biomass-based distributed power generation, Pakistan could generate enough sustainable energy to meet future demand.
